GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 778,794, dated December27, 1904.

Application led September 28, 1903. Serial No. 174,863.

To (all whom it may concern.'

Be it known that I, MICHAEL J. ORIELLY, a citizen of the United States,residing at But'- falo, in the county of Erie and Stateof New York, haveinvented new and useful Improvements in Gas-Burners, of which thefollowing is a specification.

This invention relates more particularly to that class of gas-burnerswhich are used in connection with incandescent mantles.

The objects of this invention are to improve the means for supportingthe globe on the mixing-tube, to provide means for readily adjusting'the mantle relatively to the burner, and to provide improved means forregulating the supply of air and gas and holding the same in itsadjusted position.

In the accompanying drawings, Figure l is a vertical section ot' agas-burner embodying' my improvements. Figs. 2 and 3 are horizontalsections in lines 2 2 and 3 3, Fig. l, respectively, looking' upwardly.

Similar letters ot' reference indicate corresponding parts throughoutthe several views.

A represents the main pipe or mixing-tube ofthe burner, which isarranged vertically and connected at its lower end with the air and gassupplying and regulating' devices and provided at its upper end withmeans forsupporting the globe B and mantle O.

D represents a tubular burner head or cone fitting over the mixing-tubeand provided with a downwardly facing internal shoulder (l, whichengages the upper end of the tube for limiting its downward movement.

E represents a horizontal globe-supporting ring or gallery surroundingthe burner-cone and connected with the latter by a plurality of radialarms c. This ring, the burner-cone, and the arms connecting the same areconstructed in one piece by casting or otherwise, thereby simplifyingthe construction and reducing the cost of manufacture correspondingly.The globe is held on the ring in any suitable or well-known manner- -forinstance, by means of inwardly-bent lips or hooks f, arranged on thering and engaging over the bottom iiange L of the globe, on one sidethereof, and a clamping-screw f', arranged in an ear on the oppositeside ot' the ring and engaging over the adjacent part of the iiange, asshown in Figs. l and 2.

G represents the upright rod which supports the mantle over theburner-cone. This rod is provided at its upper end with the usuallaterally-projecting arm g, having a hook g, upon which the mantle ishung at its upper end, while its lower part is arranged in a verticalopening /t in one ot' the ring-supporting arms a and is adjustablysecured therein by a clamping-screw H. At its lower end themantle-supporting rod is provided with a laterally-projectingadjusting-arm a', which is arranged below the globe-support. By means ofthis arm the mantle can be bodily moved laterally and centeredrelatively to the burnercone from the exterior of the globe by simplyturning the adjusting-arm horizontally in one direction or the other.This means of adjusting the mantle is very simple and convenient anddoes not increase the cost ot' the mantlesupport perceptibly.

J represents a conical bell or hood, which is connected at its uppernarrow end with the lower end of the mixing-tube. K represents a hub orvalve-casing, having its upper end arranged centrally within the loweror large part of the hood and connected therewith by radial arms 1. Thiscasing is provided on its lower part with an external screw-thread l, abore extending to the lower end ot' the casing and having an internalscrew-thread m and an upwardly-tapering conical valve-seat m', extendingfrom the threaded bore to the top or the casing.

L represents a disk valve whereby the admission of air into the lowerend of the hood is regulated. This valve is adjustably connected withthe valve-casing by means of an internally-screw-threaded opening Z,Jformed centrally in the valve and engaging with the external thread ofthe casing. By screwing the valve-disk up or down on the casing thespace between the same and the lower end ot' the hood may be varied forregulating the supply of air to the mixing-tube.

N represents a nipple by which the gas is delivered to the burner. Thisnipple is rigidly secured at its lower end to a gas-supply pipe by meansof an internally-screw-threaded socket n engagingl with an externalthread on the pipe. Intermediate of its ends the nipple is provided withan externally-screw-threaded portion 0, which engages with the threadedbore of the valve-casing'. The upper part of the nipple is reduced toform an annular space 7J between the same and the bore of thevalvecasing, and at its upper end the same is provided with anupwardly-tapering imperforate conical valve q, which cooperates with thevalve-seat m for regulating the supply of gas to the mixing-tube. Alongitudinal gas-conduit R is formed centrally in the nipple, whichextends from the socket at its lower end nearly to the top thereof andcommunicates at its upper end with the annular space between thecontracted part of the nipple and the bore of the valve casing by meansof ports or passages fr, extending laterally through said contractedpart. For the purpose of permitting' the gas as it issues from the portso' to pass freely to the exit of the valve-casing the outer sides of thenipple, in which the ports are formed, are cut away or attened, as shownat S, Fig. 3, thereby increasing the area of the gas-passage at theseplaces. These iiattened surfaces of the nipple also permit of drillingthe parts therein more readily, as the drill is not liable to slip, aswould be the case if the drilling were done on a round surface.

The base of the conical valve is perfectly round and somewhat smaller indiameter than the contracted part of the nipple, so as to provide auniform annular gas-passage all around the valve, which corrects anyfiuctuation or disturbance of the gas due to t'ge irregular shape of theannular passage p and causes the same to flow uniformly toward the exitof the gas-valve, thereby avoiding flickering or irregularity of tliefiame, which otherwise would be liable to occur.

By screwing the valve-casing, together with the parts mounted thereon,down or up on the nipple the gas-outlet opening on is moved toward orfrom the valve q, and the flow of gas is controlled accordingly.

T represents a clamping screw-nut which serves to hold the air and gasValves in their adjusted position and also forms part of the packingdevice for preventing gas from leaking through the joint between thenipple and the valve-casing. The clamping screw -nut works on the lowerpart of the external thread on the valve-casing and is provided at itslower end with an internal flange t. Between the latter and the lowerend of the valve-casing is arranged a pliable packing-ring u, of felt,cotton, or other suitable material. After the valve-casing has beenadjusted on the nipple and the valve-disk has been adjusted on thevalve-casing to the required position the clamping-nut is screwedupwardly until it bears firmly against the lower side of the valve-disk,

thereby firmly locking the same against accidental displacement. Intightening the nut against the valvedisk the same also compresses thepacking-ring, causing i: to bear firmly against the outer side of thenipple, thereby frictionally holding the valve-casing against turning ontle nipple and also forming a gas-tight joint between the same.

I claim as my invention-- l. A gas-burner comprising' a burner-head, asupport arranged adjacent to the head and provided with abearing-opening, and an upright rod capable of rotary adjustment in saidopening and provided above said support with an inwardly projectingmantle supporting arm and below said support with a laterallyprojectingadjusting-arm, substantially as set forth.

2. A gas-burner comprising a mixing-tube having a hood at its lower end,a valve-casing connected at its upper end by arms with said hood andhaving an internal valve-seat, a disk valve having a screw conrectionwith the exterior of the valve-casing for adjusting the same toward andfrom said hood and regulating the air-supply, and a gassupply nipplehaving a screw connection with the bore of the casing and a valvecooperating with said seat of the casing for regulating the gas-supply,substantially as set forth.

8. A gas-burner comprising a mixing-tube having an air and gas inlet atits lower end, a valve-casing arranged in said inlet and having avalve-seat, a gas-supply nipple adjust-ably arranged within said casingand having avalve which cooperates with said seat for controlling' thegas-suppl y, a disk valve adjustably mounted on the outside of saidcasing for controlling the air-supply, and a single clamping devicewhich holds both the gas-valve and the airvalve in their adjustedposition, substantially as set forth.

4. A gas-burner comprising a mixing-tube having an air-inlet hood at itslower end, a gas-valve casing arranged in said hood and provided with ascrew-thread on its exterior, an internally-threaded bore in its lowerpart and a gas-valve seat in its upper part, a disk air-valve having ascrew-threaded opening' which engages the external thread of said casingand permits of adjusting this valve relatively to said hood forcontrolling the air-supply, a gas-supply nipple having a gas-valvecooperating with said seat and a screw connection with said bore whichpermits the gasvalve and the valve-seat on the casing to be adjustedrelatively to each other for controlling the gas-supply, a clampingscrew-nut ar- IOC IGS
